<p>Select the MSVC runtime library for use by compilers targeting the MSVC ABI.</p>
<p>The allowed values are:</p>
<dl class="simple">
<dt><code class="docutils literal notranslate"><span class="pre">MultiThreaded</span></code></dt><dd><p>Compile with <code class="docutils literal notranslate"><span class="pre">-MT</span></code> or equivalent flag(s) to use a multi-threaded
statically-linked runtime library.</p>

<dt><code class="docutils literal notranslate"><span class="pre">MultiThreadedDLL</span></code></dt><dd><p>Compile with <code class="docutils literal notranslate"><span class="pre">-MD</span></code> or equivalent flag(s) to use a multi-threaded
dynamically-linked runtime library.</p>

statically-linked runtime library.</p>
</dd>
<dt><code class="docutils literal notranslate"><span class="pre">MultiThreadedDebugDLL</span></code></dt><dd><p>Compile with <code class="docutils literal notranslate"><span class="pre">-MDd</span></code> or equivalent flag(s) to use a multi-threaded
dynamically-linked runtime library.</p>
</dd>
</dl>
<p>The value is ignored on non-MSVC compilers but an unsupported value will
be rejected as an error when using a compiler targeting the MSVC ABI.</p>
<p>The value may also be the empty string (<code class="docutils literal notranslate"><span class="pre">&quot;&quot;</span></code>) in which case no runtime
library selection flag will be added explicitly by CMake.  Note that with
<a class="reference internal" href="../manual/cmake-generators.7.html#visual-studio-generators"><span class="std std-ref">Visual Studio Generators</span></a> the native build system may choose to
add its own default runtime library selection flag.</p>

support per-configuration specification.  For example, the code:</p>
<div class="highlight-cmake notranslate"><div class="highlight"><pre><span></span><span class="nf">add_executable(</span><span class="nb">foo</span><span class="w"> </span><span class="nb">foo.c</span><span class="nf">)</span><span class="w"></span>

<span class="w">  </span><span class="no">MSVC_RUNTIME_LIBRARY</span><span class="w"> </span><span class="s">&quot;MultiThreaded$&lt;$&lt;CONFIG:Debug&gt;:Debug&gt;&quot;</span><span class="nf">)</span><span class="w"></span>
</pre></div>
</div>
<p>selects for the target <code class="docutils literal notranslate"><span class="pre">foo</span></code> a multi-threaded statically-linked runtime
library with or without debug information depending on the configuration.</p>
<p>If this property is not set then CMake uses the default value
<code class="docutils literal notranslate"><span class="pre">MultiThreaded$&lt;$&lt;CONFIG:Debug&gt;:Debug&gt;DLL</span></code> to select a MSVC runtime library.</p>
<div class="admonition note">
